Table Notes:

  • AGE LIMIT. For allergies, don't use under 1 year of age. (Reason: it causes most babies to be sleepy). For colds, not advised at any age. (Reason: no proven benefits). They should be not be given if under 4 years old. If under 6 years, don't give products with more than one ingredient in them. (Reason: FDA recommendations 10/2008).
  • DOSE. Find the child's weight in the top row of the dose table. Look below the correct weight for the dose based on the product you have.
  • MEASURE the DOSE. Syringes and droppers are more accurate than teaspoons. If possible, use the syringe or dropper that comes with the medicine.  If not, you can get a med syringe at drug stores. If you use a teaspoon, it should be a measuring spoon. (Reason: regular spoons are not reliable.) Keep in mind 1 level teaspoon equals 5 ml and that ½ teaspoon equals 2.5 ml.  
  • ADULT DOSE.  4 mg. Repeat every 6-8 hours as needed.
  • 6-12 years LONG-ACTING (L.A.) DOSE. 8 mg long-acting (LA) tablet every 12 hours as needed.
  • 12 years and older LONG-ACTING (L.A.) DOSE. 12 mg long-acting (LA) tablet every 12 hours as needed.
  • Brompheniramine dosing is the same as chlorpheniramine dosing.
